The Experimental Breeder Reactor - 1 (EBR-1) is located at the Idaho National Engineering and Environmental Laboratory in Idaho Falls, Idaho. On December 20, 1951, the EBR-1 produced the first usable electricity generated by atomic energy . From the next day until it was decommissioned in 1963, the EBR-1 supplied all of the power for its own building. Three years after it was decommissioned, President Johnson dedicated the facility as a registered National Historic Landmark. The nearby city of Arco, Idaho became the first city in the world to be lit by nuclear power.
